Parsing the gas switch events is somewhat complicated, because depending on the actual model, they can be stored in different ways. The table below lists the number of gas mixes (G), tanks (T) and alarm bytes (A) supported by each model. Note that only the representative model in each group is listed. Model | G | T | A ==============|===|===|=== Pro | 1 | 0 | 1 Com | 1 | 1 | 1 Tec | 3 | 3 | 1 Aladin Tec | 1 | 0 | 2 Aladin Tec 2G | 3 | 0 | 2 Galileo | 3 | 3 | 3 Models without support for multiple gasmixes only need to set the initial gas mix correctly. Models with support for one or more tank pressure sensors can link the gas switches to the tank switches. Models with at least two alarm bytes can store a gas switch event in the second alarm byte. As can be observed from the table, some models can use several different methods to store the gas switches. The current implementation supports all of them. In the case of a conflict, the last used method always takes precedence. That's simply due to the fact that each method just sets the gasmix index, and only the final value is used. If this approach turns out to produce wrong results, it can always be fixed later. The initial gasmix is always assumed to be the first configured gasmix.
Overview ======== Libdivecomputer is a cross-platform and open source library for communication with dive computers from various manufacturers. The official web site is: http://www.libdivecomputer.org/ The sourceforge project page is: http://sourceforge.net/projects/libdivecomputer/ Installation ============ On UNIX-like systems (including Linux, Mac OS X, MinGW), use the autotools based build system. Run the following commands from the top directory (containing this file) to configure, build and install the library and utilities: $ ./configure $ make $ make install If you downloaded the libdivecomputer source code directly from the git source code repository, then you need to create the configure script as the first step: $ autoreconf --install To uninstall libdivecomputer again, run: $ make uninstall Support ======= Please send bug reports, feedback or questions to the mailing list: http://libdivecomputer.org/cgi-bin/mailman/listinfo/devel or contact me directly: jef@libdivecomputer.org License ======= Libdivecomputer is free software, released under the terms of the GNU Lesser General Public License (LGPL).
